SEOUL -- Here come the bendable smartphone displays. Samsung has announced the Galaxy Round smartphone, which the Korean electronics giant is calling the "world's first curved display smartphone."

Galaxy Round sports a 5.7-inch full HD Super AMOLED screen that will let users take advantage of a "Roll Effect" to check the date, time, missed call, and battery status information, even when the home screen is off. A separate "Gravity Effect," Samsung says, will let folks interact with the phone by tilting it. Samsung also says that when the music player is running but the display is off, the user can press the left side of the device to play the previous track or the right side to play the next track.

The phone will be sold in Korea only for now, and Samsung hasn't announced pricing or potential U.S. availability.

The news comes a few days after Samsung's Korean rival LG announced that it will start mass producing a flexible OLED display for smartphones. The flexible panels use plastic instead of glass, which allows them to be bendable.
